CUTTING AND CREASING PRESS.

Application 'filed. March 2, 1923. .Serial No. 622,414.

to a printing press which is used for cutting and creasing or to a press specially built for cutting and creasing. The invention is herein sh'own'applied to a flatbed press though it will be apparent that my invention is not limited "to this application.

This is made .up from sharp edged cutting rule .and round edged creasing rule placed edgeways in'the form which is carried on the bed and held inposition by means of wooden or metal blocks.

A sheet of box board is fed to the cylinder,'and'as it passesbetween the bed and the cylinder it is out into suitable sections to make boxes and'is suitably creased for bending at the corners of the boxes.

It is customary to leaveties or tabs connecting *various "portions of the sheets connected where :they would be otherwise entirely severed by the cutting rules, in order that sections of the sheet willbe temporarily 25 held "together until the sheet is delivered from "the press," the sheets being stripped after they are delivered Tom the press to remove "or break these ties 0r tabs. It often happens that these ties *or bands are not strongenough toprevent portions of the cut ';-and creased sheets from separating before they are delivered from the press and the present invention isfintende'd to prevent infiury-to the-sheets, -the dorm and'the press it ".suchoccurs.

The general method of cutting and creasing these sheets is described in "my Patent Alfter-the sheet is cutandbetoreit is de- 40 *l-ivered "from'the-cylinder, these out sections are likelyto fall out *and either cause trouble onlthe delivery-'orthey drop on to the dierand interfere with" cutting the next sheet. The present invention covers an easily removable shield, or series of bands at the back otthecylinder. TI-tis necessary to make this: shield easily removable in orderto make room to lift the "jacket for make ready as and 14 attached to any described in my PatentNo. 1,375,450.

In the drawings forming part-of the application *ing this time out Fig. I is a side elevation of an ordinary cutting and creasing press with my invention attached.

II is an enlarged side view of some of the parts showing the shield or bands.

Figs. III and IV are enlarged detail sec- 'tions showing a method. of adjusting the shield supporting brackets.

Fig. V is a sectional plan of the end ofone of the brackets showing a collar fo-rholdin-g the supporting rods in place.

Fig. "VI is aback view of the shield or bands and the cylinder.

In Figure I I have shown only such portlons of a press as are necessary to illustrate the application o'f my invention. Herein 51 have shown one of the side frames 15 of the press; the feed table, 2. from which the sheets are fedytheimpression cylinder 1-the sheet delivering device "Zffor delivering the sheet iromthe cylinder, and-the reciprocating bed 3,having a form 4; ofcutting and creasing rules.

rection of its arrow) and as the bed 'runs underthe cylinden'the die 4. outs and creases the sheet on the cylinder. The cut sheet now passes'on up with the cylinder at 5 and durportions are likely to fall out on tothe die, which has now come into position 6 or to the rear of the impression cylinder, or it they do not fall entirely out 4 they may come partly out. and these hang ing portions are'likely to catch on'some part of the delivery at 7 for instance, and thus throw the sheet out of position in the delivery.

At'S I have shown a shield or series of bands bent approximately to the curve of the cylinder; this shield is fastened to small supporting blocks or brackets 9 and 10, which hangout-he rods 11 and 12.

These rods are supported on brackets 13 part of the frame workof the press such as the frame members 15. Since some jobs require the shield closer time the bed to the cylinder than others, it is desirable to make it adjustable to and from the cylinder. It is also well for convenience in manufacturing to make the brackets adjustable (slightly) up and down. I have accomplished this as follows:

Bracket 13 is attached to the frame wit-h two bolts, one of which passes through a hole 16 and the other through a slot 17 in the bracket, Fig. III. Thus the bracket 13 can be swung slightly toward or away from the cylinder (after slacking off the bolts). Bracket 14 is attached with two bolts, one through a large hole 18, and the other a slot 19, in the bracket, Fig. IV. Thus, if the bolts are slacked off, bracket 14 can be adjusted towards or away from the cylinder and it can be swung up and down slightly.

When lifting the jacket for make ready, it is necessary to remove this shield bodily from the cylinder. I have made it easily removable as follows The rods 11 and 12 are held together by means of the connecting arms 20, thus the rods, arms and shield make one complete unit and can be handled as such. The rods 11 and 12 hang in slots 40, 41, in their brackets. The top rod 11 will be automatically held in position by gravity and the bottom rod is held in position by means of spring collars and lugs in the bracket, thus:

Brackets 1 1 are provided with lugs 241-. (These show best in Fig. V.) Shaft 12 is provided with a fixed collar 23, at one end and a movable collar 22 at the other end and the movable collar is held in position by means oi a spring 21. When the shaft 12 is seated in its slots the collars 22 and are also seated'against the face of the bracket, back of lugs 24:, and it is effectually held there by means of the spring 21 so that the rod cannot get out without first sliding the. spring collar along in its rod. At 25 is a pin in the rod 12 to hold the collar 22 from sliding entirely 011 the rod when the unit is removed from the brackets. Since collar 28 is fixed in the rod, it can readily be made as an integral part of the rod if it is desired, i. e., as a shoulder on the rod.

To remove the shield, the unit is grasped at any convenient place, say by the arms 20, and it is moved slightly to the right, Fi VI, compressing spring 21, until the collar 23 slips by the lugs 24. This corner is removed from its bracket, and the unit is slid to the left until the collar 22 slips by its lugs, and then the entire unit is lifted straight up and outoi the slots in brackets 13. To replace the unit the process is reversed.

This shield can be made of one continuous piece, or of a series of strips or hands, two of which are shown at 8, Fig. VI.

I have shown this device as attached to 21 bed and cylinder cutter and creaser, but it is evident that it is equally applicable to other types of cutters and creasers 'as well and it should be so considered.
